Allegro MicroSystems Corporation announces an open loop Hall-effect sensor Ed with near sealed loop performance (throughout accuracy and data transfer useage). Allegro’s ACS716 current sensor ICprovides an inexpensive and precise means for current sensing software in industrial, commercial, and communications programs. The device is offered in a footprint surface install package that allows straightforward implementation in customer applications, and is seo’ed for 3.3V supply procedure.

The ACS716 consists of a detail linear Hall sensor integrated circuit which has a copper conduction course located near the surface of the silicon die. Employed current flows from the copper conduction path, and the analog output voltage from the Corridor sensor IC linearly monitors the magnetic field generated by the used current. The accuracy with the ACS716 is maximized using this proprietary packaging configuration because the Hall aspect is situated in very close proximity to the current being measured.

High level health to current conductor dV/dt along with stray electric career fields, offered by Allegro proprietary included shield technology, guarantees low ripple with output and lower offset drift inside high-side, high voltage applications. The actual voltage on the overcurrent insight (VOC pin) allows people to define an overcurrent fault threshold for the device. When the current moving through the copper passing path (between the IP+ as well as IP- pins) exceeds this kind of threshold, the open empty overcurrent fault pin will certainly transition to a judgement low state. Manufacturer programming of the linear Hall sensor Ed inside of the ACS716 results in excellent accuracy in both analog and digital output signals.

The inner resistance of the birdwatcher path used for present sensing is typically 1 mohm, for low power loss. Also, the existing conduction path is electrically isolated through the low voltage sensor information and outputs. This enables the ACS716 family of indicator ICs to be used in applications requiring electrical remoteness, without the use of opto-isolators or other expensive isolation techniques.
